Help pay for chubs medical bills and recovery

We left for a family trip to Florida so we put our diabetic cat at an animal boarding thinking he would be safer there. They called saying chubs wasn’t eating for two days and they were thinking of taking him to an emergency animal hospital since we were out of town. We rushed back home to see our cat jaundiced, weak, and frail. They say he needs fluids, an ultrasound, antibiotics, insulin, and possibly surgery (etc.) The first picture is the day we took him he was playing and loving and the one below is when we got back where he was extremely sick. We are very shocked and heartbroken and are doing the best we can to help him get better. The costs for just the first day we’re about $2000 and with further care will be a couple more thousands. Any donations would be highly appreciated.
